Claims comparing a packaging’s environmental benefits to another product can only be made if they can be substantiated. Words like “better” and “most” can’t be used since they aren’t quantifiable. Words like “larger” or “smaller” or “more” or “less” can be used if they are quantified through the use of purchasing or manufacturing records or historical data.
- DO sufficiently qualify comparative claims.
- DO be clear about what is being compared.
- DO cite sources of data used and any assumptions made.
- DO maintain backup records to support claims.
